CHARLES R. HARVEY, OF POUGHKEEPSIE, NEW YORK.

Speciiication formingvpart of Letters Patent No. 490, dated November25, 1837.

To all whom t may concern: y

Be it known that I, CHARLES R. HARVEY, of Poughkeepsie, in the county of Dutchess and State of New York, have invented a new and Improved Mode of Weaving HairCloth,com monly-called hair seatingg and I do hereby declare that the following is a full and exact description, reference being had to the drawings annexed. y

vThe nature of my improvement consists in applying power to the weaving said cloth, especially by operating the hook (a thin wooden rod having a hook at one end by which the hair is drawn into the web) by power instead of working it by hand, as is common in the ordinary hair-seating loom.

To enable others skilledin the art to make and use my invention,I proceed to describe its construction and operation.

AAAAAAAAAAAAAAAAarethe several parts of the frame-work or superstructure of the said loom, which may be either wood or iron.

'atbbbbbbh E is theyarn-beam, to which is afiixed beam-heads, cords, levers, and weights in the 'usual mode of power-looms, as at c c c c c c c c.

F is the transverse cam and motive cani to the hook hereinafter described. The cam may be made as shown in the drawings, or by an iron casting having arms and using the rim or periphery to produce the transverse movement, as ate. The circumference of said cam is forty inches-eleven inches in a direct line on the outward end, thence transversal, deviating nine inches from the first line and embracing twelve inches of the circumference, thence iive inches in a direct line, thence twelve inches transversely back to the place of beginning.

G G G G are the driving-gears and pulleys, and may be made in any ordinary and convenient way common to any power-loom.

H H are the crank and crank-shaft.

I I are the crank-arms connecting crank H with lathe B, as at J J are the cog-wheeland pinion, the wheel being five to one larger than the pinion. Note: There is also a pinion affixed to the transverse cani-shaft on the inside of frame (and not se'en in the drawings) of the same size as thevabove pinion and driven by the above wheel, giving motion to the said shaft.

K is the treadle-shaft, upon which is affixed the treadle-cams g g g g. l

L represents the treadles, five in number, and made inthe usual way, having` cast-iron shoes at h, and attached to the frame-work at fi.

M represents the lamms or cross-treadles, seven .in number, fastened to frame at j j, and are connected with the treadles by small cords Ich, and also to jacks O O by small cords or wires at l l.

N N are the harness bars or shafts. Five of the harness are made in the usual way. The

other t'wo are made with metal eyelets or nails to form tabby edges to a satin web. They are connected with jack O O by cords m fm, and and also to springs P P by cords n a. f

O O are the jacks or small levers hung with la pin in the center, and are` connected with lamms M and harness-bars N N by cords Z Z and m fm. Y

P P are the spiral springs connecting harness-shafts N N by cords n n, and serve to draw them down to their place after having been raised by the treadles L.

Q is the churn (so called) or along tin dish, in which the server (the person who supplies the hook) holds the hair in water when weaving..

R R represent the stand or brace to support the roller C, and is fastened to frame at o 0.

S is the breast-board, against which the Servei' leans when weaving. It is sometimes supported by a brace, as at p p.

T is the transverse lever or arm working on the'transverse cam held at one end by pivotstud and braces q q q. At the'other end is affixed the pitman r, connecting it with the Wag-staff V at the point where it crosses the center of transverse cam F. A forked pivot of iron S drops on the cam and connects with the lever.

U is the stand for the outside end of the transverse cam-shaft tomhieh the slot-guide t is fastened. The said guide keeps the lever down on the cam.

V is the wao-staff made of wood, excepting a short piece at the top` which is iron, and passes through the hook X and serves to throw it through the web.

XV is the hook-slide formed by grooving the edges of two pieces of timber and placing the edges parallel to each other one-fourth et an inch apart.

X is the hook made in the usual Way, except a small mortise near the outward end, through which the top of the Wag-stal? passes. It is raised or let down by the brace u to t the web.

Y is the slide-stand fastened to the iioor and supports one end of the hook-slide.
